Byline Bancorp, Inc. is a Chicago-based bank holding company that operates through Byline Bank, a full-service commercial bank serving small and medium-sized businesses, commercial real estate sponsors, and consumers across the Chicago metropolitan area. The company generates revenue primarily through interest income on a diverse lending portfolio—including commercial and industrial loans, commercial real estate financing, sponsor finance, small ticket equipment leasing, and government-guaranteed lending—as well as deposit and treasury management fees, trust and wealth advisory services, and gain-on-sale income from loan originations and servicing. It funds its operations primarily through commercial and consumer deposits, with commercial deposits providing a significant source of low-cost funding, and pursues growth through both organic expansion and strategic acquisitions in its core markets.
